The bilge high water alarm indicator is a gauge that features both a visual and audible 85 dB alarm. The gauge is connected to a float switch mounted in the bilge, aft near the main transom and to starboard of the keel. As the water level rises, the float switch’s internal lever will lift and trigger the alarm.

Decibel Scale of Measurement: Sound power level in decibels (dB) is a logarithmic unit used to describe the ratio of sound intensity (in watts/m2 ) to the lowest sound people of excellent hearing can hear, N0. L=Sound power level (dB) N=Sound power (watts/m2) N0=10-12 watts/m2. L=10log(N/ N0)

dB Calculations. WATTS TO dB. You have a 100W amplifier and want to change to a 350W amplifier. How many more dB will you get out of your loudspeaker? Formula: dB = 10 x Log (watts1/watts2) or 10 x Log (350/100). Note the larger number is divided by smaller will give you +dB. You DO expect higher SPL, don't you? Enter 350 (watts1) Hit the ...
